Cannot pass JSON array to array

I am trying to pass my JSON array to an array called array so that I can then query the array with submission_id with value 27 to obtain the safety_rating_id, schedule_job_id, score and submission_id from this JSON https://codeshare.io/UqJMV but I'm being thrown this error

Cannot convert value of type '[JSON]' to expected argument type 'JSON'

Code to pass JSON to array:

var array: [JSON] = []

func getTask(onCompletion: () -> (), onError: ((NSError) -> ())? = nil) {

     guard let endPoint = Data.sharedInstance.weeklyEndpoint 
else { print("Empty endpoint"); return }

    Alamofire.request(.GET, endPoint, encoding: .JSON)
        .validate()
        .responseJSON { response in

        switch response.result {

        case .Success:
            if let value = response.result.value {
                let json = JSON(value)
                for (_,subJson):(String, JSON) in json {
                    if let date = subJson["start_date"].string{
                        self.date = date
                    }
                    if let building = subJson["building_name"].string{
                        self.building = building
                    }
                    if let jobId = subJson["schedule_job_id"].int {
                        self.jobIdArray.append(jobId)
                    }

                    if let tasks = subJson["tasks"].array{
                        Tasks.sharedInstance.datas = tasks
                        for building in tasks {
                            if let ratings = building["safety_ratings"].array{
                                print(ratings)

                                self.array.append(ratings)

                            }
                        }
                    }


                }

                onCompletion()
            }

        case .Failure(let error):
            print("Request failed with error: \(error)")
            onError?(error)
        }
    }      
}

append() expects a single element (JSON), but ratings is an array ([JSON]).

That's what the error message says.

To append an array use appendContentsOf:

self.array.appendContentsOf(ratings)
